The invention relates to a gripping device for automatic Machines for operating containers ^ for example! Bottles or the like, consisting of one or several, mounted on a holder and with clamping devices for gripping the upper end of the bottle neck or the like. provided gripping organs. Such a one Gripping device is particularly suitable for installation in Packaging and unpacking machines determined »

It is well known that some types of bottle are popular with customers Delivered filled with a sealing lid j which consists of a plastic capsule or the like, which is particularly useful because it is light Can be put on or taken off · If this Bottles empty for reuse

The holder 1 is attached to the lower end of a carriage which can slide on the circular conveyor of a machine for the automatic actuation of bottles of known design, which is partially shown in FIG. This circular conveyor consists of two parallel, endless chains 43a, 43b which are in engagement with two pairs of mutually coaxial pinions 44a, 44b. One of these pairs is driven by a motor (not shown). The carriage 37 slides in an element 38 fastened to the lower chain 43b and is guided over rollers 39 by uprights 4G which are firmly connected to the element 38 and a second element 41 fastened to the upper chain 43a. The carriage 37 also has a roller 45 _{? At its upper end.} which rolls on a self-contained control ramp 46. This control ramp is attached to the machine frame and causes, in a known manner, the vertical movement of the holder Ί during the rotation of the circular conveyor.

The plate actuating the plunger 18 (FIG. 1) is attached to a plate 48 via a stand 47, which via threaded bolts 49 and springs 50 with nuts 51 adjustable tension on the upper

plate 2 of the holder 1 is attached. The structure consisting of the upper plate 48, the uprights 47 and the plate 18 controlling the ram is moved vertically with respect to the holder 1 by a cam disk 52 of known design, which consists of a lower part 52a attached to the plate, the upper edge of which has a sinusoidal profile , and consists of an upper part 52b which is rotatably attached to the top plate 2 of the holder 1 »The lower edge of this upper part 52b also has a sinusoidal profile. A lever 57 attached to the upper part 52b can set this part in rotation, by which the two parts 52a and 52b and thus the plate 48 and the plate 2 counter to the action of the return springs 50 as a result of the sinusoidal formation of the edges of these in contact both parts 52a and 52b are approached and removed from each other. The lever 37 is actuated in a known manner by stationary stops © (not shown) which are fastened to the machine frame and located in the movement path of the lever. For the sake of clarity,! Ig. 2 the plate 18 and its associated parts are not shown.

Which serves to control the vertical movement of the needles plate 31 is fixed at its two lateral ends to a rectangular frame 60 which is displaceable relative to the holder 1 "Bieser blades 60 is vtrsehen at its upper end with a roller 61 * on an in Calibrated control ramp attached to the MaeaMnei frame is running.

The control ramp 62 controlling the needles is profiled so that that the plate 31 moves with respect to the holder 1 from top to bottom and then from bottom to top, when this holder is in the position where the necks of the bottles go into the hole 5 inserted and edged through the annularly curved J " 10 are clamped, i.e. when the gripping device occupies its lower position. For this purpose, the lamp 62 has a first section 62a which corresponds to the corresponding Section 46a of the Bampe 46 is parallel, a section 62b which gradually diverges from the corresponding one Section 46b of the Bampe 46 removed, a section 62c which is again parallel to the corresponding section 46c of the Bamp © 46, and finally a portion 62d which gradually becomes the corresponding section 46d of the Bamp © 46 approaches (see » lig. 4).

and this is in position · Pa holds the roller 61 the section 62a of the ramp 62, which is parallel to the section 46a, does not cause any rotational movement the plate 51 and the holder 1 and the Needle 20 assumes the position marked PI on Fig. 4 with respect to the gripping member »

Immediately after the bottle necks are clamped, the roller 61 passes through the section 62b of the ramp 62, which is remote from the corresponding section 46b of the ramp 46, so that the plate 31 moves in a straight line from the top to the bottom with respect to the holder 1 .

Ramps, so that it with respect to the bottle to no movement of the needle \ occurs during this path, however, is true (the lever 7 $ a of the valve 70 on the fixed stop 77a, so that it can flow into the bottle of compressed air (P3 on Pig. 4) After the time that is necessary to generate the pressure of the compressed air circuit, which is about 2 bar, inside the bottle, the valve is closed by its lever 75b pushing against the fixed stop 77b (position P4).

The sealing caps are held by the smaller diameter portion 24 of the sleeve 23 during pressurization required time kept on the bottles.

Simultaneously with the closure, the hollow 61 controlling the needles reaches the section 62d of the ramp 62, which gradually moves to the appropriate section 46d approaches Eampe 46. The frame 60 moves here with respect to the holder 1 upwards and takes the plate 51 with it. The plate 31 in turn takes the needle with it and this releases the bottle (Positions P4, P5 and PG) · During this upward movement the plate, the closure cap 0 remains seated on the needle until its ring Oa on the lower one Edge of the actuation tube 12 abuts «Here solder remove the needle from the locking cap (position P6), which is now in a container provided for this purpose (not shown) falls.

During the upward movement of the plate carrying the needle, the valve is opened by the action of the spring 25 closed with the wreath 19 <ie.s operating tube 12 comes into contact and the attachment piece 29 with respect to returns the valve body to its lower position. The ball 33 thereby returns to its seat 34 and thus interrupts the connection between the channel 32 and the needle 20.

If the bottle does not have a cap, bumps the needle on its downward movement to no resistance, so that the attachment piece 29 does not come into contact with the valve seat and the thumb 35 as a result the ball 33 does not lift off the valve seat. The air supply to the needles is therefore through the closure cover self-controlled, so that a loss of air in the absence of a closure cap is avoided will.
